Long Live The Burning Wire! CRI For Everyone!

We should remember that the incandescent light ban was passed by the “less government” party under pressure form their corporate friends. Yet people blame “more government”

Brainwashing complete.

Talk about a giant leap in efficiency. Great news, even if it means my high-tech LED's may become dinosaurs sooner than I expected.

I hope they don't outlaw LED's. I'm still trying to get comfortable with eventually loosing my right to buy incandescent bulbs. I like using them for interior lighting in the winter to help with heating.

how the MIT idea can be produced at reasonable prices.

The idea of holding back “invisible” parts of the light in the incandescent bulb isn’t new. See infrared coated (IRC, HIR) halogen lamps. In the bulb 2.0 the IR reflecting occurs near the filament and not at a coating of the glass bulb minimizing the thermal loss.

With a price below 30 bucks and with a lifespan of e.g. 10000 hours the incandescent bulb 2.0 may be successfully launched into the market for those who are looking for a high CRI.

In the next decades the efficiency of LEDs will grow from around 100 to 200 … 300 lm / Watt.

300 lm / Watt have been exceeded in the Cree lab (published 2014). Revenge of the LED in 2040? :smiley:

You know, we’re really cruel, heartless people.

Even this new incan technology, since it holds more heat at the source, isn’t going to make Life In General any better for Innocent Baby Chickens:

(Sometimes a heat-efficient light bulb is NOT your Friend…)

Or “Globe-shaped Heaters”. All are EU-legal euphemisms which are used as a way to continue sales of 100W Incan light bulbs over there. And now we can add “100W Chick-Warmers” to our lexicon- thanks Dimbo :bigsmile:

I’ve also noticed that due to the exemption of “special purpose” bulbs, the small-globed range-hood and refrigerator Incans are now commonly found in 40W and 60W ratings, where they used to be rare in anything over 25W. Same E27 base, just smaller glass and higher-than-before cost. Hence my comments about depth of thought among the regulators; their sieve-like minds produced dozens of holes for the truly intelligent to slip past the rules they thought were so strict.

I still use 60w Incans to allow certain reptiles to continue life. Heat lamps are ridiculous. $10 a peice for maybe 500 hours? No thanks.

Personally—I don’t want to read about “Politics” OR “Manipulation” or anyones
Theories of such.

Just tell me about these cool bulbs :slight_smile:

How To Pick Up Chicks

It really works!! Point at the pic (click for full size) if you want to unlock the secrets of picking up chicks:

(Tip: Be warmer than a CFL.)

Well… The fundamental problem of the burning wire is the fact that only the top fraction of the power it needs can be converted to Light. All the rest is heat.

When that heat is dissipated through the bulb into Baby Chickens or Chocolate Cupcakes, it gets wasted.

What these guys have done, essentially, is worked out a way to keep that heat on the filament, without (much) loss, meaning it adds to the power needed to make (much more) light; and less heat gets out.

Meaning, for once, “It’s Cool”, will apply!!

All this and 100 CRI? Who don’t love that?

Edit: OH, and because it’s still (I think) a Resistive load, we won’t need funky drivers unless we just want them. Be still, my heart!

I have heard the new Nichia 319 series will START at 105 CRI and have a vF of 1.01V! In the mean time, I still miss sub dollar incandescent 100W bulbs….

If a man wants to burn a wire at home on his own time, then it’s between him and his electricity provider.

I deleted this post because I was a bit too impulsive :-)

Yep- some like it hot and who are we to take away their happiness? Incans hold a definite advantage inside during the wintertime but that seems to have been overlooked by the nutjobs who just want them to go away completely. Perhaps they just don’t like doing seasonal “emitter swaps” :stuck_out_tongue:

Phil

There’s not really much need to swap where I live (Canada). By the time you no longer want the heat from incandescents, the days are already so long that very little artificial light is needed.

The article is vague. Hopefully MIT has improved on the infrared recycling technologies that already exist on the market, as seen in GE H7680 HIR bulbs and Osram 64447 IRC bulbs, etc.

A 100W LED will heat up a perfectly opaque and insulated box just as much as a 100W incandescent

The chickens will be OK, we will just have to provide them with sunglasses!

(All forms of energy eventually “descend” to heat)

True, but have you ever seen any 100w LED bulbs in a store? The highest I recall are somewhere around 13 watts, usually less. Can you even buy 100w A19 LED bulbs anywhere? That would be one helluva bright bulb! (And probably fry itself in no time.)

Just buy a halogen IR bulb, you can get them in many wattages from 25-500W. The incandescent was used because it happened to be available, but there are many ways to skin a cat, you can buy USB warmers, you can get space heaters in different wattages, you can use insulation as mentioned and so forth.

I personally would not have listened to my corporate overlords and banned the incandescent, i would have put a $5 tax on each bulb, and used that money for research and development of future technologies and other energy conservation programs.

You’re right, it would be one bright bulb. Hence the need to outfit the chickens with shades. :stuck_out_tongue:

This from the Lowes deal alert thread. I couldn’t pass on these because they were so cheap. Never know when I might want to start a chicken farm!

Thats exactly what i was referring to. I used one when i lived in college to keep Bort warm at night.
Since they are on clearance there is obviously no cold chicken epidemic stoking demand.
